133 Appearance ColorPhysical PropertiesTechnical ServiceIndexAdhesionIn order to perform satisfactorily, coatings must adhere to the substrates on which they are applied. In practice, three different test procedures are used to assess the resistance of paints and coatings to separation from substrates: Cross-Cut TestThis test method specifies a procedure for assessing the resistance of paints and coatings to separation from substrates when a right-angle lattice pattern is cut into the coating , penetrating through to the method may be used for a quick pass/fail test. When applied to a multi-coat system, assessment of the resistance to separation of individual layers of the coating from each other may be AdhesionThis test method covers the determination of the Adhesion of organic coatings such as paint, varnish, and lacquer when applied to smooth, flat (planar) panel surfaces.
134 ISo Class.: 4 / ASTM Class.: 1 B The coating has flaked along the edges of the cuts in large ribbons and/or some squares have detached partly or wholly.
